Incoming Mail in WSS 3.0

Good Day,

We are trying to activate the incoming mail for WSS 3.0.

The settings on the Central Admin are as follows:

Settings Mode = Automatic

Directory Management Service = No

E-Mail Display = <ServerName>.<DomainName>.ph

Safe E-Mail Servers = Accept form all

We are able to configure with no problems and even set up the Document Library Settings, The problem is the when trying to send a mail to the email address, <LibraryName>.<DisplayAddress>, Nothing happens, no items appear on the library nor any error is diplayed/returned.

Is there something wrong with the Set-up or is there any way to check if there are any errors encountered as to why the library doesn't receive the mail?
